Radio Broadcast Areas

Radio
broadcast is one method used by the NWS and other public and private agencies
for disseminating the EMWIN
datastream.

Most EMWIN VHF broadcasts are (and will be) the result of
cooperative efforts by other public and private agencies. There are
several NWS frequencies available for use, but
rebroadcasters may also obtain frequencies from other agencies/organizations,
such as the National Guard. For the NWS frequencies only, a cooperators
agreement and license documents are available here.
All other agencies/organizations will have there own licensing requirements and
agreements.
